Sheesh. Such a silly diatribe. Or is it really a plea for help?

Of course heat sources are needed. If the Mantle was not hot, there
wouldn't
be any subduction. Slabs have buoyancy because the mantle is hot.

I explained the basic physics of this mode of convection in posts
to Timberwoof. I suggest you review it.

Once again you've gone off half cocked and made a fool of yourself.

Again.
